SIMON COOPER, OF BROOKLYN, NEW YORK, ASSIGNOR TO NASHUA CARD GUMMED & COATED PAPER COMPANY, OF NASHUA, NEW HAMPSHIRE, A CORPORATION OF MASSACHUSETTS.

Specification of Letters Patent.

Patented May 16, 1916..

Application filed April 14, 1915. Serial No. 21,315.

Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in' Machines for Making Reinforced Paper, of which the following is a specification.

This invention relates to the manufacture of reinforced sheet material, and especially concerns mechanism or machinery whereby both longitudinal and transverse strands may be secured between two webs of sheet material. For convenience of description I shall hereinafter refer to the sheet material as paper and to the strand material as twine. It is to be understood, however, that I do not limit myself to these particular materials.

One of the objects of my invention is to provide a machine which will manufacture a loosely woven fabric of twine, and combine this fabric with two layers or webs of paper, using a coating of glue or other suitable adhesive to unite the whole.

Another object of the invention is to provide a machine which embodies what might be termed anattachment, or a complement, to a regulation loom, the shuttle of the loom supplying the transverse twine while the longitudinal reinforcing twines are controlled by the loom, harness and reed mechanisms to supply the reinforcement to the paper as a true woven fabric, although very loosely woven.

With these and other objects in view my invention consists in the improvements which I shall now proceed to describe and claim.

Of the accompanying drawings: Figure 1 is a side elevation, partly. broken out or in section. illustrating my. improvements as applied to or connected up with a regulation loom, said figure showing no more of the loom than is necessary to an explanation of my improvements. Fig. 2 represents an elevation from the right of Fig. 1, but broken out to reduce the width of the figure. Fig. 3 is a detail elevation of the loom reed, the wires being spaced differently from the usual spacing in a loom. Fig. 4 represents a detail section on line 4-4 of Fig. 1. Fig. 5 is a detail side elevation of one of the twine carrying chains. Fig. 6 represents a section on line 6-6 of Fig. 5. Fig. 7 is a detail elevation of one of the latches or twine guiding devices.

Similar reference characters similar parts in all of the views.

Referring first to Figs- 1 and 2, a portion of the frame of a suitable loom is indicated at 12, said loom having its usual lay 13, reed 14, and a beam 15. The warps which become the longitudinal strands of my reinforcement are indicated at a. It is to be understood, of course, that the alternating warps a are shifted vertically by the-usual harness mechanism so that the shuttle on the lay 13 will cause the filling twine to produce, with the warps a, a woven fabric. It may be explained here, however, that I do not employ the reed mechanism to beat up in the ordinary sense, but only to carry the weft or transverse twine to position to'be taken by grippers hereinafter described and carried along to the nip of the rolls which combinethe paper with the loosely woven fabric.

Mounted in a suitable frame 16 are upper and lower rolls 17, 18, which I term the combining rolls. They are mounted respectively in bearings 19 and 20. At each end of the roll 17 is a sprocket 21.

Secured to the beam 15 of the loom are two brackets 22 which overhang the point to which the lay 13 is swung by its usual mechanism to beat up, such position be ing indicated by full lines in Fig. 1. These full lines compared with the dotted lines simply conventionally indicate the swing of the lay. Pivotally mounted in the overhanging end or portion of each bracket 22 is a bracket 23, the pivot being indicated at 24.- Said pivot is practically a rock shaft;

indicate and it has an arm 25 to which is connected one end of spring 26, the other end being secured to a suitable fixed point. Rotatably mounted in each pivoted bracket 23 is a small sprocket 27. A chain 28 is mounted on each pair of sprockets 21, 27, a suitably mounted adjustable idler being indicatedat 29. The length of the links of the two chains 28 'control the spacing of the lateral or transverse strands or twine, the said twine being carried or beat up by the reed of the loom to position where they will be gripped or nipped by the adjacent diverging ends of the chain links as they pass'over the sprockets 27 the filling twine being released again as the chains pass around the sprockets 21. Referring particularly to Figs. 5 and 6, it will be seen that the alternating links of the chain are Wide and narrow. While one link has a relatively 'wideglug 30, the two next overlapping links pivoted thereto at 32, have relatively narrow lugs 31. These lugs are so formed as to preferably slightly overlap at their ends when the chain is traveling straight, and consequently when twine is introduced be tween the divergingends of the lugs as indicated in Fig. 1, then when these ends forming jaws close up because of the continuous traveling movement imparted to the chains, the twine will be gripped or nipped between the one end of a lug 30 and the adjacent ends of the lugs 31. To avoid the liability of severing the twine the corners of the lugs are preferably rounded as indicated in Fig. 6. In order that the sagging of the lower stretches of the chains shall not open the .jaws or nippers and consequently release the filling twine until it is time to be released, I provide guide strips 33 which may be mainly supported by the beam 15 of the loom and connected thereto, and which may also be connected to the frame 16 so as to practically act as ties to hold the loom and the frame 16 properly spaced. The supports or connections for these strips 33 with the frame 16 may comprise stud pins 34 indicated in Fig. 2.

In Fig. 1 I indicate three idler guide rolls 35, 36, 37. An upper strip or web of paper 1), leading from any suitable reel not necessary to illustrate, passes over idler 35 and around the upper roll 17. Another strip or web of paper 0 leads from any suitable reel, over the idler 36, and under and around lower combining roll 18. The idler 37 simply guides the combined sheetsand the reinforcement out from the machine. As the lower web 0 passes under the roll 18, it receives-a coating of glue or other suitable adhesive from a roll 38 which is supplied with adhesive by a suitable pan 39. The shaft of the roll 38 is mounted in bearings 40 which are vertically adjustable to enable the attendant to quickly separate the glue roll from the paper, especially when the machine stops running, so that the paper will not stick to the glue roll. This adjustment of the glue roll is effected by providing a'vertical screw 41 which engages the lower portion of each vertically adjustable bearing 40, each screw 41 being mounted in bearings 42, between which bearings is located a nut 43 fitting the threaded portion of the screw. The nut carries a worm wheel 44 which is actuated by a worm 45 carried by a shaft 46 having one or more hand wheels 47. The attendant, by rotating shaft 46 can quickly lower the glue roll or return it to position.

To enable the combining rolls to be quickly separated either for the introduction of the webs or for any other purpose, I mount the upper roll 17 in vertically adjustable bearing blocks 48. Extending under each bearing block 48 is an eccentric 49 carried by a shaft 50 having a handle 51. By means of the two handles the eccentric 49 can be quickly actuated to lift the bearing blocks 48 and so raise the upper roll 17.

To facilitate the entrance of eachstretch of filling material between the chain grippers, I provide guides 52, one at each side of the machine. For convenience of description I have termed these guides latches.

Each guide or latch swings, 'beingpivoted at 53 to a short arm of pivoted bracket 23. It has a curved face 54 and a hookor toe 55, and is normally held in -the position indicated in Fig. 1 by a spring 56 (see also Fig.

7 a. suitable stop 57 limiting the forward cated in Fig. 3. In other words, at each end. of the reed a wide enough opening is left to momentarily receive the small sprocket 27 and the two or three links of chain passing around that sprocket. After the shuttle has been received in its box at one end of the lay, and the reed has beat up and swung away, the next pick of the shuttle causes the filling thread to be looped under hook or toe 55 of the guide or latch at that side of the machine, and the traveling chain causes two link ends to bite that loop of the twine and carry it along. Whenithe shuttle is given the next pick and traverses to the other end of the lay, a similar operation is effected in connection with the guide or latch at the other side of the machine. .By the time the shuttle .has returned to the position first-mentioned, the traveling chains have carried the loop along and released it loose woven. The lugs 30, 31, of the chains or rather the ends of those lugs constitute aws or grippers which grasp edge portions of the fabric, inasmuch as the portions of the transverse strings which are taken off by said jaws or grippers are practically at the edge of the fabric. These traveling grippers transfer the fabric in loose woven condition to the combining rolls which take the fabric from the grippers and combine it with the paper.

As has been explained, each bracket 23 is pivotally mounted on a bracket 22. The object of this is that, in case the shuttle should fail to go into its place at one end of the lay, and should be forced against the bracket by the reed of the loom, said bracket 23 can swing back on its pivot without damage to the machine. This is an important feature of my invention because the action of the shuttle just described is liable to occur frequently.

It is to be understood that the chains 28 are driven continuously, and that when the next of the adjacent links acting as jaws have gripped the twine, the chains have moved far enough to advance them the distance of one link by the time the shuttle has been shot over to the other side of the loom. The twine which has been held in the hook or toe 55, is automatically removed from said hook after having been held in position while the chain 28 is advancing to guide the loop of the twine at the proper height into the next succeeding jaw space of that particular chain.

Having now described my invention what I claim is:
